[Pharo-project] Question on KeyMapping

Hi, is there a reason for, when dispatching among targets in KMDispatcher, 1- the instanceTarget is at the back of the list of keymapObservers (so that you can't override a class shortcut with an instance one (except randomly, see 2) ?) 2- the list of keymapObservers is a Set ? (so that target matching order is as random as possible, given that's a first matched dispatch ?) Thierry
